To all whom it may c0n0ern.-' I

Be it known that we, WILLIAM P. S'IYMUS, Jr., and AUGUST; F.KREUTZBERG,citizens of the United States, residing in the city, county,and State of New-York, have invented'certain new and useful Improvementsin Car-Seats and Similar Constructions, fully described and representedin the following specification and the accompanying drawings," forming apart of the same.

The object of the present invention is to provide an improved car-seatof that class in which the back is supported by arms lyingin parallelplanes and so arranged as to'reverse the back in shifting it for facingin opposite directions, the especial object of the inven tion beingtoprovide an improved construction by which danger of catching the fingersbetween the arms in reversing shall be avoided, and,further, to providesuch a construction in which the two arms shall lie side by side ineither normal position of the'seat, so as to have the appearance of butasingle arm. The first result is attained by the use of pairs ofreversingarms so constructed that they are not separated at their inneredges between the seat and back in reversing, thus affording no spacefor the fingers to enter,

-and these arms preferably are of the same width and lie one upon theother above the seat in either normal position of the back, so as tohave practically the appearance of one These arms are preferably socombined with the seat as to shift the latter in reversing the back, asusual in such constructions, and they are also preferably used incombination with a foot-rest shifted by the arms in reversing the seat,so as to bring the restin toposition for use at either side of the seat,according to the direction in .which the back is faced.

The invention includes also improved looking devices by which the backis automatically secured in either normal position when similar sectionshowing the back reversed from the position shown in Fig. 1. Figs. 5 and6 are, respectively, side and edge views on an enlarged scale, showingthe locking devices. Figs. 7 and 8 are, respectively, side and edgeviews of oneof the arms.

Referring to said'drawings, A represents the frame of an ordinarycar-seat provided with seat-sills B, on which the seat 0 rests,

the sills and'seats being inclined, as usual in such constructions, soas to change the incline of the seat as it is shifted. Pivoted to theside frames A'by pivots 10, at each end of the seat, are a pair of armsD D, the upper ends of which are pivoted to the seat-back E, the backbeing shown as provided with a plate 11, having projecting studs 1,forming pivots for the arms. It will be understood, however, that theback may be pivotally mounted on the arms in any other suitable manner.The arms are pivoted to the seat frame and back on opposite sides of thevertical center, as shown clearly in Fig. 3, lines joining the pivots ofthe two arms thus crossing each other.

As will be seen from the drawings, the arms D. D in the preferredconstruction shown are duplicates, being reversed. in assembling, andtheir. construction is as follows, referring particularly to Fig. 7 and8: The arms have straight portions extending from the seat to the back,these straight portions intersecting and lying one upon the other in thenormal position of the arms, so that, be-

- ing of equal'width, there appears from the side to be but a single armin either normal position of the back, the bent pivoting portions at thelower ends lying opposite the seat. These intersecting straight portionsof the arms are of such width, and the arms pivoted at such points, thatin reversing the seat the arms are not separated at their inner edges,and all danger of catching the fingers between them is avoided. Each ofthe arms is provided with two stops for the other arm, so that each armprovides a support at one end for the other arm in the two normalpositions. In order that the two arms may lie one upon the other in thenormal positionsof the back, these stops are in line with the oppositeedges of the arms. These stops may be formed in any suitable manner,either by securing stop pieces or pins to the arms or by forming thestops integral therewith by bending or reducing the thickness of thearm; but the construction shown is preferred, in which, as shown clearlyin Figs. 7 and 8, the arm is reduced in thickness throughout the greaterportion of its length, so as to form shoulders at its upper and lowerends, these shoulders extending parallel and in line with theoppositeedges of the arm, so that they form extended bearing-surfaces for theinner edges of the other arm. The arm D has shoulders a b, and upon oneedge, just below the shoulder (1, is provided with a notch c, for apurpose presently explained, and on. opposite sides, at the end, withlocking-notchesd e. The arm D is provided with corresponding shoulders0/ b and notches c d e. i

.If the seat is not to be shifted or no footrest is to be used, it willbe understood that the arms D D may terminate at the pivots 10, but inthe construction shown, which includes the features of a shifting-seatandfootrest, these arms D D are provided with extensions ff below thepivots 10, and these extensions carry pins 2, which enter slots 3 in theends of the seat, so as to shift the latter as the back is reversed, andthese extensions ff also actuate the foot-rest, as presently 'to bedescribed. 1

The function of the notches c o is to permit the arms D D to come intothe same plane and lie exactly one upon the other throughout their widthwhen the seat-back is in either of its normal positions, these notchesreceiving the portion of the pivot-pin 1 of the other arm that liesoutside the shoulder a. It will be understood that these notches are notabsolutely essential, as the same results maybe secured otherwise, butthe construc-i tion shown is simple and efficient.

The locking devices eoacting with the notches d e and d e consist of apair of catchlevers 13, spring-pressed by spring 14, so as to hold thehook-catches at the ends of the levers normally in the notches e d or de on opposite sides of the two arms D D. These two levers move together.

sition, as shown in Fig. 4.

1, the upper ends of the arms D D and the locking-levers are covered bya cap 12, provided with a keyhole, through which the key is passed tothe arbor 4. It will be understood that any other suitable lockingdevice may housed, and that it a locking device not requiring thenotches d e and d c be used the construction of the arms D D may befurther simplified. The locking device shown, however, is simple andetiicient and in itself forms a feature of the present invention.

'lhe'footrest F is provided at its opposite ends with bowls 15, whichpass through camslots 16, inclined downward from both sides to thecenter of the frame, the foot-rest thus being mounted in the slots.These bowls 15 carry projecting studs 7, which enter slots 8 in leversl7, pivoted to the frame and provided at their upper ends with headslying between and engaged by the extensions ff, so that the levers 17are rocked in opposite directions by these extensions as the arms D Dare shifted to reverse the back. I

The operation of the construction will be understood from a briefdescription in connection with the drawings. Then the seat is to bereversed from the position shown in Fig. 1, the levers 13 must be rockedto the right in Fig. 1 by a key on arbor 4, sd as to remove the hooksfrom the notches 6 cl in the ends of arms D D, and as the back is swungover the arms D D slide on each other as the seat is moved, but even inthe central position shown in Fig. 3 are not separated above the seat,so as to permit of the catching ot' the fingers. In the position shownin Fig. 1 the arm D is supported by resting against shoulder to on thearm D and the arm D by resting against the shoulder 12 on the arm D; butas the reversal of the back is completed from the position shown in Fig.3 and brought into the position shown in Fig.4 the arm 1.) comes to restagainst the shoulder a of the arm D and the arm D against the shoulder11 of the arm D, and as the back reaches its fully re versed positionthe spring-pressed levers 13 spring into the notches de in the ends ofthe arms and lock the latter in this reversed po- The shifting of theseatO and of the foot-rest F in reversing the back will be clear fromthe drawings, the seat 0 being moved to one side or the other on theinclined sills B, so as to cause it to project at what is the front. ofthe seat in each position and at the same time change the angle oftheseat, this result being accomplished by the pins 2, working in theslots 3 in the seat, and the rocking of the lever 17 carries bodying theinvention without departingfrom the latter, and the invention is not'tobe limited to this exact construction; I

and describedgas applied to car-seats, ,it,will

be understood that itis applicable alsoto other seats and similarconstructions employing areversiblc member.
